Scow Consulting Arborists, LLC Disease and Pest Diagnosis, Hazard Evaluation, Restorative Pruning Advice, Value Assessment 1744 Franklin Street Unit B Santa Monica, CA 90404 (818) 789-9127 4/24/17 (rev) Nevis Capital, LLC (applicant) c/o Maggie Teng 335 North Berry Street Brea, CA 92821 SUBJECT: Revised Preliminary Arborist Report for 2111 and 2125 Canyon Rd., Arcadia REFERENCE: 1) Arcadia Municipal Code, article IX, chapter 7 Tree Preservation 2) “Report on Existing Trees”, 11/15/07, Pieter Severynen BACKGROUND The applicant is proposing the construction of two new single-family dwellings, one on each parcel. There are protected oak trees of various species on the site, requiring an oak tree report in accordance with the City of Arcadia Tree Preservation Ordinance. We visited the site on 11/11/16 to assess the trees and to evaluate anticipated construction impacts and mitigation measures. The following report is based on our observations while on site, on discussions with the applicant, and on the site plan provided by the applicant. ASSIGNMENT • Record necessary data for all qualifying oaks on the project area, to be defined, including the following information: • Indicate each oak’s location on site plan provided by others (we are not surveyors, and locations not surveyed will be noted as approximate). • Measure and record for each oak: Species Trunk diameter1 at standard height Canopy spread Canopy height (approximate) Health and structural condition Disposition • Complete an oak tree report for the subject project that meets the requirements of the City of Arcadia. • Compare impacts between 2007 proposal and current proposal for use in CEQA assessment 1 Terrain may limit ability to physically measure some trees 2111 and 2125 Canyon Rd. 4/24/17 Jan C. Scow Consulting Arborists, LLC 2 OBSERVATIONS Site description: The subject site is located in the upper Sierra Madre area of Arcadia, and is situated between Clamshell Canyon and Chantry Flat Road. The site is bordered by Canyon Road to the east, a residence to the north, and undeveloped vegetation to the south and west. Some lots on the other side of Canyon Road have also been developed for residential use. The site is a steep, undeveloped, eastern facing slope with primarily native vegetation, poison oak, and mature native trees. Project description: The subject property consists of two parcels, with a single-family dwelling proposed for construction on each lot, near to and fronting on Canyon Road. Each home will have an attached garage accessible from Canyon Road, and a common open patio will connect the two homes. Grading (mostly cut) will be extensive on both parcels, except that the eastern 1/3 of the southernmost parcel will remain undisturbed. Each parcel will have a substantial crib wall with bench drains built upslope of the homes. All remaining land above the proposed crib wall will be left undeveloped. All utilities will connect from Canyon Rd. Tree description: There are sixteen protected trees of various species on or near the property (fifteen oaks and one sycamore) as indicated in the following Tree Inventory. One of the oaks is off the property to the west. A full inventory of the protected trees is listed below (and in the attached Field Inventory Data sheet), and all tree locations are shown on the accompanying Protected Tree Plan. As the inventory shows, the protected trees are a mixture of various native oaks (Quercus berberidifolia, Q. agrifolia), native oak crosses, and a single sycamore. Furthermore, there are approximately 100 additional oak trees on this property that will not be disturbed in any way by the proposed project, as we understand it2. Summary: Total Number of protected trees3 ................................................................................ 16 Number of protected trees recommended for removal ................................................. 3 Number of protected trees with encroachments ........................................................... 4 Number of protected trees not impacted…………………………………………………...9 Tree safety: We have not evaluated trees on this property for safety. Without a thorough and focused “risk assessment,” it is difficult to estimate the likelihood that a tree may fail and cause damage to life or property. Even with such an evaluation, there are no guarantees that a tree will not fail unexpectedly. Trees are dynamic living organisms subject to many influencing factors. All trees are potentially hazardous, regardless of their apparent health and vigor. It is impossible to be certain that a tree is absolutely safe. NOTE: Tree 219 has significant safety issues that concern us. This tree should be evaluated for safety, and remedial actions should be taken to enhance its safety if it is to be protected in place. Some of this work, primarily pruning, should be done PRIOR to any construction work being performed. Pruning work should be carried out by a highly qualified, and well-trained contractor who is approved by the City in consultation with the Project Arborist. While pruning can reduce the risk to these homes, it will not remove all risk. To further enhance safety, an engineered support system has been proposed and will be evaluated by the Project Arborist in consultation with a structural engineer. 2 This is based on a previous inventory that was done by our office in Dec. 2011 (see attached inventory) 3 Fifteen oaks and one sycamore tree. 2111 and 2125 Canyon Rd. 4/24/17 Jan C.

Scow Consulting Arborists, LLC 4 IMPACTS This project has been redesigned to reduce impacts and to conform to CEQA approvals from a previous application based on a 2007 report (see reference 2). A comparative analysis of the impacts of the two projects is attached. We have added several trees in our analysis that were not in the previous report. Three of these will be removed or impacted by this project, and would have had similar impacts in the previous project had they been included4. Impact assumptions: The analysis of construction impacts in this section is based on assumptions that: 1) The applicant has accurately described all relevant work to be done. 2) The mitigation measures described below will be implemented by the applicant, and monitored by the City of Arcadia, to prevent unnecessary impacts to the protected oaks. 3) The proposed project design will not change significantly. 4) We have correctly identified where the property lines are. 5) Tree locations are mapped correctly. Tree removals: Two protected oaks (trees 218 and 221) and one protected sycamore (tree 301) will be removed during construction of this project. Construction impacts: Four protected oaks (trees 201, 219, 302, and 303) will be impacted during the construction of this project. Their impacts are as follows: Tree 201- This protected oak will be significantly impacted by excavation and grading for the proposed crib wall, bench drain, and structure to the south of the tree. This may require some clearance pruning as well as significant root loss. This is considered a major impact. Tree 219- This protected oak will be significantly impacted by excavation and grading for the proposed crib wall, bench drain, and structures to the east of the tree. This tree will also require significant risk reduction pruning to reduce the risk of catastrophic failure. Safety pruning should be done before construction activity begins. These are considered moderate impacts. Tree 302- This protected oak will suffer impacts due to excavation and grading for the proposed crib wall and bench drain to the north of the tree. This is considered a minor impact. Tree 303- This protected oak will suffer impacts due to clearance pruning necessary to make room for the proposed structure to its west. This is considered a minor impact. Assuming that no work will take place outside of the proposed construction boundaries, and that recommended protective fencing is installed as indicated on the enclosed Protected Tree Plan, the remaining protected oaks will not be impacted by this project. 4 These are smaller trees that may not have been large enough to consider in 2007. 2111 and 2125 Canyon Rd. 4/24/17 Jan C. Scow Consulting Arborists, LLC 5 MITIGATION Removal mitigation measures: It is our understanding that all tree removals from this site have been mitigated for by a conservation agreement for Parcel 3 with the City. Specific impact mitigation measures: These steps are provided specifically for the unique conditions of this project. These are considered the minimum oak protection measures which the applicant will carry out in order to maintain the impact levels described in this report. Oversight of tree 219 activity- Before any work is conducted in the vicinity of oak tree 219, the project arborist will be called to discuss the steps needed to ensure safety and maximize tree viability. Proposed order of operations for Tree 219 The project hinges to some degree on how this large oak fares during the design and construction process. It is suggested that the following steps be carried out in the following order: Step 1. Project Arborist will work with a structural engineer (to be hired by applicant) and an approved arborist with structural support experience (to be hired by applicant) to design a suitable structural support system5 that will be anchored by the crib wall and will support the oak’s trunk to reduce the chances of whole tree failure. Step 2. Pruning of this oak will be carried out with the Project Arborist in attendance to oversee pruning and judge the effect on the safety of the tree. This pruning work must be done by an arborist approved by the Project Arborist and must be done prior to any other work within 100 feet of this tree (for safety reasons). Step 3. When grading or excavation is to take place within 50 feet of this oak in any direction, the Project Arborist will be on site to examine the extent of root damage and judge the viability and safety of the tree based on roots encountered, slope stability, etc. If the impacts associated with this work still appear to be acceptable, proceed to step 4. Step 4. Construction of crib walls and the tree’s structural support system will be done in consultation on site with the Project Arborist. It is the owner’s responsibility to ensure that the project arborist is notified prior to initiating these activities. This is a safety issue as well as an oak tree preservation issue. Protective fencing- Protective fencing shall be installed at the top of the site to protect trees 219 and 302. Fencing shall also be installed surrounding trees 220, 222, and 303, and trees 201 and 202. Please see the enclosed Protected Tree Plan for exact locations of recommended protective fencing. Protective fencing around trees in construction zones is the best possible means of minimizing impacts related to construction if it is done properly. The purpose is to keep the oaks’ root zone free from disturbance of any kind throughout the period of construction activity. The greatest benefit from the use of protective fencing is the prevention of soil compaction. Other benefits 5 It is critical that this support be designed and approved prior to additional work. It is possible that during the construction of the crib wall it may be determined that the tree needs to be removed. 2111 and 2125 Canyon Rd. 4/24/17 Jan C. Scow Consulting Arborists, LLC 6 include protecting branches and trunks from equipment-related breakage and injury, and preventing root damage from spillage of construction chemicals, grading, etc.. 1. Fencing will be installed in the locations shown on the enclosed Protected Tree Plan prior to any grading activity or construction on the site. Fencing will be chain-link, at least 5 feet high, and held securely in place by steel stakes driven directly into the ground. 2. There shall be no gates, openings, or easy access into the fenced protection zones. All protective fencing shall remain intact until construction is completed. 3. No workers or equipment shall enter the fenced areas. 4. No storage, waste disposal, equipment clean-out, outhouse, or vehicle parking will be allowed within the fenced area. Clearance pruning- Where clearance pruning is required (for trees 219, 302, 303, and any other trees not anticipated for clearance pruning at time of writing this report), all pruning will be carried out by an ISA Certified Arborist. All pruning shall conform to ANSI A-300 standards at a minimum. Risk reduction pruning on tree 219 must be done by an approved expert (see note under Tree Safety). Ground cover- In order to further protect the oak trees being retained during construction, it will be helpful to lay a ground cover around the trees during and after construction. Appropriate ground cover for this site would be a 3-4 inch thick layer of organic mulch composed of wood chips or oak leaves, being sure to keep the mulch a few inches away from the trunks of all trees. The mulch should cover all ground inside the trees’ protective fencing during construction, and be extended to meet the trees’ canopy driplines once protective fencing is removed. General impact mitigation measures: The following measures should be applied where they are relevant. If specific measures above conflict with any of these general recommendations, specific measures shall supersede. 1. All work conducted in the ground within the protection zone of any protected tree should be accomplished with hand tools only. (The protection zone is defined as the area within a circle with a radius equal to the greatest distance from the trunk to any overhanging foliage in the canopy). 2. Where structural footings are required and major roots will be impacted, the footing depth should be reduced to 12". This may require additional "rebar" for added strength. An alternative would involve bridging footings over roots and covering each root with plastic cloth and 2-4" of Styrofoam matting before pouring concrete. 3. Any required trenching which has options as to the trench path should be routed in such a manner as to minimize root damage. Radial trenching (radial to the tree trunk) is less harmful than tangential trenching because it runs parallel to tree roots rather than diagonal or perpendicular to them. If roots can be worked around, cutting of roots should be avoided (i.e. place pipes and cables below uncut roots whenever possible). Whenever possible, utilize the same trench for as many utilities as possible. Generally, roots with a diameter of two inches or more should be saved. Digging should be done manually to avoid tearing, puncturing, or otherwise damaging the bark that covers the roots. Roots should be covered and kept damp while trenching is being done, and reburied as quickly as possible. 2111 and 2125 Canyon Rd. 4/24/17 Jan C. Scow Consulting Arborists, LLC 7 4. "Natural" or pre-construction grade should be maintained for as great a distance from the trunk of each tree as construction permits. At no time during or after construction should soil be in contact with the trunk of the tree above natural grade. 5. In areas where grade will be lowered, or where footings will be dug, some root cutting may be unavoidable. Cuts should be made cleanly with a sharp saw or pruning tool, far enough behind the damage that all split and cracked root portions are removed. The cut should be made at right angles to the root so that the wound is no larger than necessary. When practical, cut roots back to a branching lateral root. Do not apply any pruning wound treatment to cuts. 6. When removing pavement, as little disruption of soil as necessary should be attempted. 7. Pruning of oaks should be limited to the removal of dead wood and the correction of potentially hazardous conditions, as evaluated by a qualified arborist. Pruning oaks excessively is harmful to them. Removal or reduction of major structural limbs should be done only as required for actual building clearance or safety. If limbs must be removed, cuts should be made perpendicular to the branch, to limit the size of the cut face. The branch bark collar should be preserved (i.e. no “flush cuts”), and cuts should be made in such a way as to prevent the tearing of bark from the tree. All pruning should be done in accordance with ANSI A300 pruning standards. No pruning wound treatment (e.g. “Tree Seal”) should be applied. 8. Keep all activity and traffic to a minimum within the protection zone of the trees to minimize soil compaction. 9. It is important that the protection zone not be subjected to flooding incidental to the construction work, or to disposal of construction debris such as paints, plasters, or chemical solutions. No equipment fueling or chemical mixing should be done within the root protection zone. 10. In general, it is best to minimize the amount of environmental change which trees will be subjected to. This includes drastic changes in watering practices from historic conditions, especially drastic increases. 11. Care should be exercised not to allow equipment to physically damage the tree’s trunk, root crown, or lower scaffold branches during construction. This includes but is not limited to 1) impact damage by scrapers, buckets, or hoes; or 2) damage by tires, wheels, or tracks from operating in close proximity to trees. CONCLUSIONS This project will remove two healthy native oaks and one native sycamore, but the conservation of the third parcel is significant and should mitigate for the losses. The protective measures will help to keep the remaining oaks safe from damage if followed appropriately. The only concern here is with the largest oak, tree 219. It is important that the project arborist be involved in efforts to save this tree, as safety is a significant concern, as well as the tree’s survival. It is our opinion that the impacts from this revised project are no more significant than the impacts from the previously proposed (2007) project design. In fact they are less significant. 2111 and 2125 Canyon Rd. 4/24/17 Jan C.

Clients may choose to accept or disregard the recommendations of the arborist, or seek additional advice. Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees are living organisms that fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborists cannot guarantee that a tree will be healthy or safe under all circumstances, or for a specified period of time. Likewise, remedial treatments, like any medicine, cannot be guaranteed. Treatment, pruning, and removal of trees may involve considerations beyond the scope of the arborist's services such as property boundaries, property ownership, site lines, disputes between neighbors, landlord-tenant matters, etc. Arborists cannot take such issues into account unless complete and accurate information is given to the arborist. The person hiring the arborist accepts full responsibility for authorizing the recommended treatment or remedial measures. Trees can be managed, but they cannot be controlled. To live near a tree is to accept some degree of risk. The only way to eliminate all risks is to eliminate all trees. Please note the following important considerations: • You should never authorize or do any work on any tree unless you are certain of that tree’s ownership, and you have confirmed that you solely own the tree, or that anyone else having a claim to the tree has given you permission in writing authorizing your proposed action. • Before removing a tree, be sure it is your tree to remove. • Trees on property lines belong to both properties. • Working on trees hanging into or over your yard that belong to a neighbor may result in “unreasonable damage” to their tree and could expose you to litigation. 2111 and 2125 Canyon Rd. 4/24/17 Jan C.
